Levenhuk Zoom 7-21 mm Eyepiece
Varied focal-length eyepiece for any telescope

With Levenhuk Zoom Eyepiece you can change the focal length during your observation without actually changing the eyepiece. It can replace several conventional eyepieces. That's why these varied focal-length eyepieces are so popular among amateur stargazers. Thanks to the twist-up rubber eyecup you can use this filter even if you wear glasses.

The optics are made of high-quality glass that provides incredible sharpness, clarity and vividness of the image. The scale engraved on the shell allows you to easily and quickly set the focal length you need within the 7-21-mm range.

The eyepiece is also threaded (M38x0.75) for a T-ring (purchased separately), which allows you to use an SLR camera for astrophotography.
